About this entry

74% of key specs known. Missing: hardening, bracelet links, end links, link attachment, clasp micro-adjust.

Bombfrog's quartz diver with a shrouded, tuna-style case and a recessed unidirectional bezel; the brand says its construction follows the DIN 8306 diver's-watch standard. Brand specs (current spec table): 316L steel, "12-6 H 48mm | 3-9 H 45mm" (recorded as lug-to-lug and diameter), total height 12mm, screw-down engraved caseback, 7mm screw-down engraved crown, AR-coated sapphire, 60-click aluminium bezel, Seiko (Epson) VX42 quartz with date, 22mm lugs, 500m, Super-LumiNova Grade C3 (the table says "Luminova Grade C"), serial number; 112g on the neoprene strap, 192g on the steel bracelet (folding clasp, 5 removable links). The Professional 500 is also sold as a 35mm Damen (ladies) model with a VX12E, recorded separately. Variants: Steel; Black Edition (black IP-coated case, same specs); and unit editions on the steel case with the unit's logo on dial and caseback: Kampfschwimmer (German Navy combat swimmers), EOD Basic, Senior and Master (US EOD technician badges, black dials), EOD Officer (blue dial) and Minentaucher (German Navy mine-clearance divers) with retro yellow or silver dials, all publicly priced. The unit-edition pages use an older spec text giving 46mm and 12.3mm, and the dimension drawing on the steel bracelet listing shows 47mm across (apparently including the crown); the current 45mm/12mm spec table is recorded. The Kampfschwimmer bracelet page names a "Sicherheitsverschluss" (safety clasp) where the standard pages say "Faltschließe" (folding clasp). Store pages show prices "inkl. MwSt." (including VAT).
